, KF'SSLER, or CLEVELAND HErGHTs-omo'; ASSIGNORS mournnruc'rroiv s'rovE COM- 7 PANY, OF CLEVELAND, OHIO, A CORPORATION- OF OHIO CHIMNEY DRUM FOR HEATERS This invention relates to heaters of the rum type, and it has for its primarypurpose the provision of a construction which makes it practical and economical to employ glass cylinders in the chimney drums of such It may be briefly explained that the chimney drums of heaters of the kindin question are composed of a top member, a bottom member or so-called cone plate, a cylindrical shell or chimney drum which is inter:

posed between the two members, and means for drawing or tying the top and bottom members together so as to hold the cylini drical shell or drum between them.

Early attemptsto employ glass cylinders as a part of the chimney drums of heaters of the above mentioned type met with little success. These glass cylinders when made in the usual manner are not at all uniform, varying considerably in height and in diam eter and are usually 'out'of round, so that when such cylinders were clamped between them the top and bottom members of the heater they would immediately be placed under strain or would assumesuch condition when heated, and. as a consequence thereof would crack or break. I

As indicated above, it is the main object of the'invention to overcome the foregoing difliculty; and further objects are to provide simple, cheap, substantial and durable means for tying the top and bottom membersof the chimney drum together without imposing undue pressure or strains upon the glass section and which'is of such a naturethat it renders the drum comparatively economical of production and quickand convenient of assembly. I p v r The above mentioned objects, with others hereinafter appearing, are attained in the construction illustrated in the accompanying I drawings whereinFig. l is a side elevation of a heater incorporating the'invention; Fig. 2 is a central vertical section throughthe drum substantiallyon the line 22 of 1, the view being taken as though-looking in the direction of. the arrows associated with said line, the present view beingon a scale somewhat enlarged over that of Fig. 1;;and

heaters. -',Figs. 8 and. 4C are details on further en-..

larged scales showing, respectively, the connection between the upper end of one of the tie members and the chimney top, andthe lower end of said tie member and the cone plate.

The stove, comprises a, base l i shatissup- 1ported a suitable distance above the floor y legs 2, and to its rear sideis connected by Y a hinge 3 the drum that "isdesignat ed gen erallyby the reference numeral 5. Ailatch 6jdeta'chably connects the front sideof the drum to the corresponding side of the base,

and pivotally connected to the top of the drum, in a manner presently to be'desc ribed,

is a bail 8 involving a -hand grip 9.

The chimney drum,.in .the present instance,

ismade up of a perforated metallic section 10 and a glass cylinder 11. The two are held against relative rotary motion by a projection provide respective ledges 20and 21, the former receiving the lower end ofthe metallic chimney sectional O, and the latterbearing upon a ring 22 that is engaged within an an nulardepression 28 of what is knownasthe cone plate 24. The outer wall of the depres sion- 23 iscomparatively deep and is curved outwardly at itsupper end and mergesinto. a

flaring skirt 25 that extends downwardly over and rests upon the upper end of the stove base 1. Inwardly of the depression 23, the cone plate is inclined downwardly and inwardly to where it is connected to a collar 25 which cooperates with a part 01 the burn er that is designated generally by the reference numeral 26 and is suitably supported within the stove base.

Connecting the top member 15 and the cone plate 24, at diametrically opposite sides of the chimney drum, are tie bars 28. At their lower ends these bars are deflected inwardly at an angle to their vertical body portions corresponding to the incline of the inner portion of the cone plate and bear directly upon the said plate, and beyond such de y flected portions the terminals of the tie bars are flanged downwardly'at right angles and areprojectedthroughslotsin said plate. Such lower ends of the tie bars will be referred to as feet 29, and extending through registering holes in said feet 29 and in the cone plate are bolts 30 to the lower ends of which are applied lock washers 31 and nuts 32. Heads 33 are formed on said tie bars by turning their upper ends outwardly at right angles, said heads having conical depressions 3 1 through the bottoms of which extend threaded apertures. The chimney section 10 has diametrically opposed notches 35 for the accommodation of the outer ends of the heads 33, and riveted within holes in the top member 15, above the heads 33, are the reduced upper ends of thimbles 36 having threaded apertures with which are adapted to be aX- ially aligned the threaded apertures in the heads 33. Screws 38, carrying washers 39 of compressible material beneath their heads (see Fig. 3), are threaded downwardly through the thimbles 36 and through the heads 33 for connecting the parts together.

In the assembly of the chimney structure, the feet 29 of the tie bars 28 are connected in the manner above described to the cone plate 2 1. The ring 22 is then dropped within the depression 23 of the cone plate and the glass cylinder 11 is placed upon the ring 22. The lower end of the chimney section 10 is then engaged over the reduced upper end of the glass cylinder 11 and brought to bear upon the shoulder 20, the parts being positioned with the lug 12 of the glass cylinder in the notch 13 of the chimney section 10, and with the outer ends of the heads 33 of the tie bars within the notches 35 of said chimney section. The top 15, with the screws 38 retracted, is placed upon the upper end of the chimney section 10 and a definite weight is placed on top of the member 15, so that the parts are held together under a predetermined pressure until the screws are tightened. It has been found that to let the parts rest of their own weight alone, one upon another, they are too loose when the chimney is assembled.

WVith the weight in place the screws are then turned downwardly until they enter the conical depressions in the heads 33 of the tie bars 28, such depressions aligning the threaded apertures of the heads 33 with the screws. Through continued turning, the screws are advanced until their heads are stopped by the riveted upper ends of the thimbles 36. The assembly of the drum is thus completed. By reason of the fact that each screw 38 is threaded through both the thimble 36 and the head 33 of the corresponding tie bar 28, it is impossible to draw the parts together more firmly than when resting of their own weight upon one another, it being understood that the thimbles 36 are secured against turning with respect to the top member 15.

Thus it will be seen that our invention provides a very simple, economical and convenient means for tying the top and bottom members of the chimney drum together without imposing strains upon the glass section 11. Also, it is clear from the construction above described that the chimney section 10 is held by the tie bars against turning with respect to the cone plate which, in turn, bears a fixed relation to the base of the stove by reason or its hinge connection thereto, and the reason for locking the glass section 11 against rotary movement with respect to the metallic section 10 through the instrumentality of the lug 12 and notch 13, as above explained, is that in commercial practice, certain matter is embossed on the glass section and it is desirable to maintain the same in a given relation to the remainder of the structure, as at the front thereof.

An important advantage arising from the use of the metal ring 22 and the metallic drum section 10 at the opposite ends of the glass drum section 11 is that, inasmuch as the ring 22 and section 10 are flexible, they adjust themselves to any out-of-roundness of the drum section and thereby prevent undue strains being imposed upon the latter as a result of such an abnormal condition.
